Fixed an issue where the calendar could look like it was missing classes after changing the selected location.
- Saved calendar filters now only apply to the instructors, rooms, classes and class types available at the location you are currently viewing.
- The instructor picker no longer keeps selections from a previous location.
- Class type options now reflect only the types actually offered at the current location.
- Filters saved for a location are properly cleared when you switch, so they can no longer reappear after the page reloads.
